LTC1403ACMSE#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1403ACMSE#TRPBF is a 14-bit, 2.8Msps serial analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 10-lead MSOP package. It operates on a single 3V supply with active power dissipation of 12mW and features a Sleep shutdown mode reducing consumption to 10µW. The device accepts differential inputs within a 0V to 2.5V unipolar range and includes an internal 2.5V bandgap reference. Key performance metrics include a full power bandwidth of 50MHz, 80dB common-mode rejection, and guaranteed operation from 0°C to 70°C.

• Single 3V supply operation with 12mW active power dissipation
• Integrated 2.5V internal reference with external overdrive capability
• Sleep (10µW) and Nap (3mW) shutdown modes

Analog To Digital Converters (ADC) Applications

• Automotive systems
• Communications equipment
• Data acquisition systems
• Uninterrupted power supplies
• Multiphase motor control

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the AC grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the source documentation matches the specific lot marking L TADF for this variant.

Analog To Digital Converters (ADC) Selection Notes

Select this part when 14-bit accuracy at high speeds is required under low power constraints. The internal 2.5V reference simplifies design but can be overdriven by an external source between 2.55V and VDD for improved noise performance. Ensure the driving circuit settles within 39ns to maintain full throughput rates.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1403 family, which also includes 12-bit variants (LTC1403) and different temperature grades (C, I, H). The AC designation specifically denotes the commercial temperature range extension compared to the standard C grade, while maintaining identical electrical specifications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same package and specification include other LTC1403A variants such as LTC1403AIMSE#TRPBF or LTC1403AHMSE#TRPBF, differing only in operating temperature ranges.
